Letter Converter

Letter Converter is a free, open-source and simple-to-use application for Windows computers, which provides you with a fast way for converting text to uppercase (all big letters) or lowercase (all small letters).

It's ideal for users who are working on projects for school or business and don't have a case converter integrated in their preferred text editor.

There is no installation pack involved. Instead, Letter Converter is wrapped in a single executable file that can be saved anywhere on the hard drive or copied to a removable storage unit. This way, you can easily launch the tool on any PC. However, make sure to download and install .NET Framework unless you already have it, since it cannot work without Microsoft's software framework.

When it comes to the GUI, the application has a single window that shows an empty box for pasting text, along with two buttons for converting it to lower or upper case. The operation is instantly performed, as soon as you click the button.

However, it's a good idea to have the original text safely stored in another place, in case you make all the characters big or small by accident. You should know that the program doesn't implement features for converting only part of the text; if you make a selection before clicking one of the buttons, the tool will process the entire text regardless.

There are no buttons integrated for storing everything in the Clipboard or exporting the text to file. On the other hand, you can select the parts of text you're interested in by clicking and dragging with your mouse pointer or pressing the arrow keys while holding down Shift and/or Ctrl, and copy it using Ctrl+C or by right-clicking to choose the Copy entry.

To sum it up, Letter Converter works as expected, quickly converting any text you enter to upper or lower case. However, if you're looking for more sophisticated features, you should try other applications.
